Enables cross-compilation of the VM for ARM.

Browse Source 
Uses the "toolset" feature of gyp to build the dart VM
for ARM, but restricts building of snapshot generation
to the host machine.

For generated source files, it also changes to using
LIB_DIR instead of SHARED_INTERMEDIATE_DIR to avoid
generation of duplicate Makefile rules (gyp doesn't
know that generated source files from toolchains it
thinks are different will be the same.)
